ANCHORING MEANS FOR CONCRETE BODIES.

Application filed February 11, 1922. Serial No. 535,883.

To aZZ whom it may concern:

Be it known that I, J'AMEs MARTIN FOX,

a citizen of the United States, residing at have holes in them, lengthwise, of sufficient 727 \Vest Main Street, Madison, in the county of Dane and the State of Wisconsin, have invented certain new and useful Improvements in Anchoring Means for Concrete' Bodies, of which the following is a v specification.

Yo The object of my invention is to provide a combination whereby and by means of which wooden plugs located in different parts of a structure or article of manufacture, some of which parts are composed wholly or in part of a concrete mixture may serve to fasten such articles together.

To accomplish this the wooden plugs of any kind of wood desired and of any size and shape desired are placed in the troughs or moulds in the desired positions before the concrete mixture hardens and sets.

' Figure 1 of the drawing shows my wooden plug invention as applied to a section of portable pavement the right half showing a wooden plug in position with the concrete set around it and the left half end with the wooden plug shown before the concrete mixture is, placed in the-mould.

Figure 2 shows my invention as applied to a railway concrete tie andFigure 3 as applied to a fence post of concrete structure.

Preferably, the shape of the wooden plug will be larger in the center and, tapering smaller at the ends. However if desired this shape may be reversed or changed to any shape desired that may be deemed more efiicient.

Also the wooden plugs when desired may size to take the nail or spike when driven into them and effect a solid and secure fastening' without producing enough pressure to cause a bursting or cracking of the concrete formation.

Also if desired LO' prevent decay at the ends of the wooden plugs instead of or in addition to painting metal washers may be applied to'c over the'e-nds 'of the wooden plugs the washers to be provided with holes in the center of any size and shape desired through which holes the nails or spikes are driven into the wooden plugs the heads of nails or spikes being in position over and in contact with the washer.

The wooden plugs if desired may he so placed as to go all the way or ony part way through the posts or ties or other parts of a concrete-cement structure for purposes of fastening. V

As my invention, I claim:

In an anchoring device comprising a concrete 'body having a wooden plug inserted therein while the concrete is plastic, whereby said plug serves for attaching means for securing articles together.
